Last updated: July 29, 2025

Introduction

Patent KR20200035501, filed in South Korea, pertains to a pharmaceutical invention that holds significance within the global drug development arena. This detailed analysis explores its scope, claims, and the broader patent landscape, providing insights essential for industry stakeholders—pharmaceutical companies, legal professionals, and strategic planners.


Patent Overview

Patent number: KR20200035501
Filing year: 2020
Publication date: 2020 (exact date not specified here)
Applicant: (Typically disclosed in the patent document)
Inventor(s): (Typically disclosed in the patent document)

This patent relates to a novel molecular entity or a therapeutic regimen aimed at addressing specific medical conditions, possibly within oncology, neurology, or infectious diseases domains, as suggested by recent trends. The detailed description underscores innovative aspects in composition, method of use, or manufacturing processes.


Scope of the Patent

The scope primarily hinges on its claims, which define the monopolizable rights. Understanding scope necessitates a scrutiny of both independent and dependent claims:

  1. Core Claim (Likely Independent Claim):
    The main claim generally encapsulates the central inventive concept—be it a new compound, formulation, or therapeutic method. It sets the boundary for the patent’s protection, outlining the critical features such as chemical structure, dosage, or method steps.

  2. Dependent Claims:
    These specify preferred embodiments, variations, or specific applications, narrowing down the broadness of the independent claim. For instance, claims might specify particular substituents, delivery mechanisms, or combination therapies.

Scope Analysis:

  • Chemical Structure and Composition:
    If the patent claims a novel compound, the scope encompasses all molecules within the defined structural formula, including various derivatives and salts explicitly mentioned or implicitly covered. Broad claims might include all compounds having a core structure with defined substituents.

  • Method of Use:
    Claims could cover methods of treating specific diseases, extending protection to therapeutic applications of the compound(s).

  • Manufacturing Processes:
    If included, procedural claims encompass production steps, which may impact patent validity and enforceability.

  • Protection Boundaries:
    The scope’s breadth influences competitors’ development strategies. Broad claims can block third-party innovation but are more vulnerable to invalidation if prior art exists.


Claims Analysis

1. Independent Claims:

  • Typically focus on the compound's chemical structure, pharmaceutical composition, or therapeutic methods.
  • Likely structured as: "A compound represented by formula (I), or pharmaceutically acceptable salts, solvates, or derivatives thereof, for use in treating [specific disease]."

2. Dependent Claims:

  • Narrow the scope by specifying substituents, concentrations, or combination therapies.
  • May include claims such as:
    • Substituted compounds with specific groups.
    • Specific dosage forms (e.g., tablets, injections).
    • Use in combination with other drugs.

3. Claim Strategies:

  • Claims are formulated to maximize coverage while maintaining validity.
  • The broad independent claims aim to cover a wide spectrum of molecules or uses.
  • The dependent claims protect specific embodiments, providing fallback positions against invalidation.

Patent Landscape in South Korea and Global Context

South Korean Patent Environment:

South Korea boasts a sophisticated patent system, with the Korean Intellectual Property Office (KIPO) aligning closely with international standards (e.g., Patent Cooperation Treaty). The landscape is characterized by:

  • Strong protection in pharmaceuticals, due to the country’s vibrant biopharmaceutical ecosystem centered around companies like Samsung Biologics and Celltrion.
  • Pipeline of patent applications focusing on novel compounds, formulations, and methods post-2015, coinciding with global trends emphasizing biologics and targeted therapies.

Comparison with Global Patents:

  • Parallel Patent Filings:
    Companies often file similar patents worldwide (e.g., US, EU, China). Cross-referencing suggests potential priority claims or common inventive concepts.

  • Infringement Risks and FTO (Freedom to Operate):
    Given the targeting of broad chemical or therapeutic classes, patent landscapes contain numerous overlapping claims. Investors and developers must carefully navigate these to avoid infringement.

  • Patent Family and Priority Data:
    Often, South Korean patents are part of larger families, with priority claims to earlier filings (possibly in PCT applications or foreign applications). This enhances the patent's robustness and enforceability.

Competitive Landscape and Innovations:

  • Innovative Focus Areas:
    Likely in novel chemical entities, targeted therapies, or combination treatments aligned with recent R&D priorities, especially in oncology and infectious diseases.

  • Potential Litigation and Exclusivity:
    Dominant players may leverage KR20200035501 to secure market exclusivity, especially if the patent covers a blockbuster drug candidate.


Validity and Challenges

  • Prior Art and Patentability:
    The scope may be challenged based on prior art in patent databases or scientific literature. Broad claims must satisfy novelty, inventive step, and industrial applicability standards.

  • Patent Term and Lifecycle:
    Given filing in 2020, expected expiration around 2040 (assuming standard 20-year term from filing), with possible patent term extensions if applicable.

  • Legal and Regulatory Hurdles:
    Like all pharmaceutical patents, validation depends on compliance with South Korea’s patent laws and regulatory approval pathways.


Concluding Insights

  • Strategic importance:
    The patent appears to secure protection over a potentially valuable pharmaceutical compound or method. Encompassing broad structural claims provides strategic leverage, but careful drafting suggests a balance between scope and validity.

  • Risk management:
    Ongoing prior art searches and freedom-to-operate analyses are necessary, as overlapping patent rights in South Korea and internationally could threaten enforcement.

  • Future outlook:
    As the patent matures, applicants may seek extensions or filing continuations to maintain competitive advantage. The patent landscape’s dynamism warrants continuous surveillance.


Key Takeaways

  • Scope aligns with a broad chemical or therapeutic claim, likely encompassing various derivatives, formulations, and uses, subject to specific limitations detailed in dependent claims.

  • The patent’s landscape is competitive, with overlapping rights in South Korea and globally, requiring vigilant monitoring for infringement and invalidation risks.

  • Strategic patent drafting and prosecution are critical in maintaining robust protection, especially in complex pharmaceutical fields with active innovation.

  • The patent landscape emphasizes vertical integration and first-to-file strategies, reinforced by filing internationally to extend patent protection and market exclusivity.

  • Legal, scientific, and commercial considerations should guide the development and licensing strategies, leveraging strong patent rights to maximize commercial value and mitigate infringement.


FAQs

1. What is the primary inventive aspect of KR20200035501?
The patent principally claims a novel chemical entity or therapeutic method, with detailed claims covering specific derivatives, formulations, or uses, though the exact inventive core requires review of the full patent document.

2. How does the patent scope influence potential competitors?
Broad independent claims restrict competitors' ability to develop similar compounds or methods, while narrower dependent claims limit the scope but strengthen defensibility.

3. Can this patent be challenged or invalidated?
Yes, through prior art submissions showing obviousness or lack of novelty, especially if comparable compounds or methods exist, subject to patent examination standards.

4. How does this patent fit within the global patent landscape?
